Be 1t known that I, WIL IAM HENRY TROUT, a citizen of the United State's, residingat, Milwaukee, in the county of Milwjau fkee and State of Wisconsin, 'havejinrented lar saws, whichji's'simple in construction and efficient in operation. l Onej dfthe; more "specific, objects" is toj'pro'vide "improved means for holding the? saws uponthe sawshaft'in' rigid alinementfiwhilefatthe same time permitting them'toslide'jfreely upon the shaftand to approachelos'ely to one another. 1 Another, object is to provide means for lubricating 't'hefcoacting surfaces betwee'n'the saws and 'the'shaft', whereby the saws may be'readi'ly moved along the shaft, and; whereby danger" of either wasting or slinging the lubricant'and necessity of fre- The present application is a division of the application from which Patent No. 1,203,9l0 matured,

The lateral bearing surface upon the shaft 10 is secured by providing two elongated keys 3, which are fixed in the grooves 4 of the collar 12 and slide in key-ways or slots in the shaft 10. The ends of the keys 3 extend beyond the ends of the collars 12 a considerable distance, but preferably not more than half the width of the collar 12. It will be noted from Figs 2 to 5 inclusive that four key-ways or slots 9 have been provided in the shaft 10, and that four corresponding grooves 4 are formed in each collar 12, but each collar carries keys 3 in I only two diametrically opposite'grooves l in which the keys are secured by means of screws 5. This enables the keys 3 on any collar 12 to be received inthe corresponding alined grooves 4 of the adjacent collar 12 when the two saws 11 are moved 'closetogether so that the keys do not in any way interfere with the approaching of the saws until the adjacent ends of the saw-collars 12 abut. It is, of course, realized that while only four grooves have been shown, any other desirable number of grooves may be provided, the principle being that the keys3 are fixed in one saw-collar 12 in alinement with vacant grooves 41; in adjacent saw-collars 12. I

In order to properly lubricate the coact- 7 ing surfaces of the shaft 10 and saw-collars 12'during sliding of the collars along the shaft, the collars 12are provided with'sets of'chambers 6 between the grooves 4 thereof, these chambers being packed with oil-saturated waste 7 to which lubricant may be supplied through holes 8, see Fig. 6.

While Ihave herein shown and described the most improved form of the invention, it

should be understood that not all of the features are essential thereto, or necessarily made in the exact form shown, but various changes and modifications may be made without departing from the spirit of this invention, and'it is to be understood, therefore, that the invention is not otherwiselim- 'ters Patent Furthermore, the old form ited than by the scope of the appended claims. a

It is claimed and desired to secure by Let- 1. In combination, a shaft, a V saw-collar slidably mounted thereon, a circular saw mounted on said collar, and one or more keys fixed in grooves in said collar and sliding in grooves in the shaft, said key or keys. being longer than said collar. t

2. In combination, a shaft having two grooves therein, a pair of saw-collars having 7 each two grooves therein, and a pair of keys mounted in the grooves of the'respe'c'ti've collars; each key sliding in one of the grooves in the shaft and having an end projecting beyond the saw-collar in which it is fixed and adapted to be received Within the vacant groove of the other saw-collar.

3. In combination, a rotating shaft having a longitudinal groove therein, and a pair of saw-collars nonrotatably linounted on said shaftand one of which is slidable thereon,

said slidable collar havinga key sliding in 7 said groove and projecting beyo'ndthe end ,of'the collar, and the other collar havinga recess adapted to receive the projecting end of said key whereby the two collars are enabled to approach close together.

' 4:. In combination, a rotatable shaft, and a pair of collars nonrotatably mounted thereon, one of said collars being slidable longitudinally on said shaft, one of said (301- lars having one or more laterally projecting elements abutting upon'the shaft and adapted to form an extension of the bearing-surface, andthe other having one or more recesses adaptedvto receive said projecting element or elements. p V

5. In combination, a rotating shaft, a pair of" saw-collars nonrotatably and slidably mounted thereon, each of said collars having one or'more laterally projecting elements on theside adjacent to the other collar adapted to form extensions of the bearing-surface of the collars upon said shaft, and each collar having also one or more recesses adjacent to the shaft which are in line with and adapted to receive the projecting'element or elements on the other collar,-whereby said'collars are enabled to approach close together;

6. In combination, a saw-shaft having one or more pairs of longitudinal grooves therein, and a pair of saw-collars slidably mounted on said shaft and each carrying one or more keys which project beyond the collar, each key mounted on one collar engaging in one of the grooves of said shaft and lying opposite to a vacant space on the other collar, whereby it passes under said collar when the two collars are approached.

7. In combination, a saw-shaft having four equally spaced longitudinal grooves therein, a pair of saw-collars slidably mounted on said shaft and each having four collar, whereby each pair of keyscarried by corresponding grooves in their naves, and one collar is adapted to be received'vvithin four keys which are longer than the saw-colthe vacant grooves of the other one as said 1; lars and two of Which are mounted in one collars are approached.

1' pair of diametrically opposite grooves in one In testimony whereof, the signature of the collar and the other two in the other pair of inventor is aflixed hereto. v diametrically opposite grooves in the other WILLIAM HENRY TROUT.
